Comment on attachment 323402 [details] config.log That's not the config.log for the configure script that emitted the "cannot compute" message.
Created attachment 323404 [details] config.log Right, here it is.
4.7 flags used with 4.6. Sorry for the noise.
we hit this in every upgrade. we really need a generic solution.
Why aren't you just using -march=native? The only reasons I know of where you'd want to spell it out is for distcc or to set -mtune for versions prior to 4.6 where there was no core2 cost model. Neither seems to apply in your case. I'm not sure how we could strip flags unknown to the compiler being built. Until it's built we don't know what flags it'll accept and by then it's too late.
for bootstrap builds, we can build up the xgcc first, then filter all of the cflags using that
True, but how do you replace the flags in the middle of the build?
Specifically unrecognized options by gcc-4.6 are: cc1: error: unrecognized command line option '-mno-bmi2' cc1: error: unrecognized command line option '-mno-avx2' cc1: error: unrecognized command line option '-mno-lzcnt'
